Bicyclobutane is an organic compound with the formula C4H6. Consisting of two fused cyclopropane rings, it is one of the most strained compounds isolatable on a large scale. It is a colorless easily condensed gas.〔K. B. Wiberg, G. M. Lampman, R. P. Ciula, D. S. Connor,P. Schertler, J. Lavanish "Bicyclo()butane" Tetrahedron, 1965. Vol. 11, pp. 2749 - 2769.〕 The first reported bicyclobutane was the carboxyethyl derivative, C4H5CO2Et, which was prepared by dehydrohalogenation the corresponding bromocyclobutanecarboxylate ester. The parent hydrocarbon was prepared by conversion of bromocyclobutanecarboxylate ester to 1-bromo-3-chlorocyclobutane, followed intramolecular Wurtz coupling using molten sodium:〔Gary M.
